Catalytic environment of WT and C54S SmeCOSe showing different ligands. (a) Catalytic environment of WT SmeCOSe showing a bound sulfate molecule (PDB entry 6g5z). The catalytic cation (green) and its environment are also shown. (b, c) The choline binding environment in the different chains of WT (b) and C54S (c) SmeCOSe (PDB entries 6g60 and 7pth, respectively). Leu499 from a second protomer is omitted for clarity. Different colors for choline have been used to highlight the different orientations that are found. The catalytic cation is also shown (green). (d) HEPES binding environment in C54S SmeCOSe (PDB entry 7ptj).
